To'all whom it may concern;-

"Be""tf know"' hatil, ALBERTEL JAooBs, a 133 W. Susquehanna-"Ave.,1 Philadelphia, in the county'of Philadelphia and State of lEennsylvania, have invented newanduseful Improvements in Goggles, of whlch the following'is aspecification; This invention relates to goggles, andfhas for a primarybbject "to provide an eficient and clearly practicable device for prO ectmg the eyes of from the" obnoxious effectsof volatile for-- eign matter; t p Another obje'ctfof "the invention 1s to pro protector forlocomotive engineers, and like operators of high speed' ve-' tion for excluding 'dust, sand-,'and like particles from the eyes, yet permitting of afree i andunob structed vision, through the v1s1on lens- 0f the conditions.

Similar charactersof reference denote corresponding parts throughout the several views of the drawing. j In the drawings the numeral'l designates the preferred form of the goggles comprising the present invention, the same consisting of a bent-metal inner frame 2, which is shaped to conform to the face ofa wearer. The frame 2 includes a forehead-engaging portion 3, curved'extremities 4, and a nose recess 5. Thus 11; Wlll be V .frame'ls "in an operativeposltlon, the'sar'ne seen that when the Will'completel'y encircle the eyes of one wearingthe goggles.

and'is of the same general contour as the frame 2. Secured to the outer frame 8, in any preferable manner, is a visionlens 9, which is adapted to be located immediately in front'of the eyes of one Wearing the protector. p

Numerous objections can be laid to the ordinary goggle glass, chief of which resides in the fact that moisture or the like will accuniulate upon its exterior surface, so that a.

clear vision through the. sameis very diflicult. To overcome this primary disadvan tage, and others, the

ity-of'spaced aperturesIO, the latter being in the nature of openings extending entirely through the lens. ow in order to prevent.

foreign matterfrom entering the openings lens 9 employed by the present lnventionis-provided with a plurah 10, the present invention contemplates ejecthose 14:, which leads to ing a current of air across each of said openlngs in a direction transverse to the1r'1ong1- tudlnal axes, whereby' dust particles will be c efiectively prevented from enterlng the goggles. To this end the invention provides an air ejector 11, consisting of two plates 12,

which are interposed between the opemngs 10, and are secured in any preferable mannerto the outer frame 8. The plates 12 are slightly spaced apart so as to provide at their outer en s openings 10. I Connected with the member 11 1s a flexible air supply (notshown) whereby air under pressure will be conducted from said supply to the ejector 11." Due to the flared construction of the nozzles 13, the air will be forced in curtain formation across the openings 10,

under sufficient pressure to eft'eotivelypi'event dust particles from passinlgfthrough said openings. Itfwill be manifest that through the provision of the openi'ngs'lO, and means for forcing the, air across the same, a clear visio'nmay times through the lens 9, and also the eyes will be protected from the effects of the elements. v H j V In order to clearly retain the goggles in ad'- justed position upon the head of the wearer,

the inner frame 2 is provided witheyes 16,11

which are secured the extremities of straps 17. One of the straps 17 isprovided with a buckle 18, for the reception of the free extremity of the other straps may the head.

strap 17 whereby the .and is employed to guide the tube 14 with relation 'to the goggles, so that the tube will be held in a supported position, and prevented from dr'opplng 1n the line of vision of-th'e goggles. a

From the foregoing it will be seen that there is providedmechanism whereby the objects of the invention have been achieved,
